CLEANER.

Application filed J'u1y 2,

To all whom it may concern:

Be it known that I, ERNEST J. DoHNAL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Cleaners, of which thefollowing is a full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification.

My invention relates to utensils, and more specifically to handleddevices such as dusters, mops, and the like.

The primary object of my invention is to increase the adaptability andserviceability of too-ls of this type for use under varying conditions,and especially in various positions.

Further objects and advantageous details of construction will becomeapparent as description proceeds.

In the accompanying drawings :v

Fig. 1 is a side elevation of a duster or mopacco-rding to theinvention, showing the different positions of use;

Fig. 2 is a plan view of the head portion, the fabric part of thecleaning element being omitted for the sake of clearness;

Fig. 3 is a section on line 33 of Fig. 2; and

Fig. 4 is a section on line 4 4: of Fig 3.

In the embodiment of the invention selected for illustration, the handle10 is slotted at 12 and the slot is lined by a. simple U- shaped clip ofspring steel 14:, preferably provided with outwardly turned lugs 16 atthe ends of the arms The fabric portions 18 are held by the twisted wirehoop 20, the ends of which come together at 22 and are turned at rightangles into parallelism ,to form a projecting end 24 preferably enclosedin a ferrule 26. I prefer to make the ferrule of brass, to secure.smooth sliding action against the sprin'g steel liner 1 1. All the partsare held firmly in assembled condition by asingle one-piece fitting bentto form a bight 28 constituting a transverse journal for the hoop 20.From the central portion of this bight, fiat flanks 3O diverge and mergeinto the central portions of arms 82, each forming a substantiallysemi-circular channel to receive the handle 10. A bolt or rivet 3 1completes the assembly. Beside the flanks 30, the outer ends of b ight28 are 1924. semi No. 723,618,

curved in as at 36 to merge into the arms 32, and also form a morecomplete bearing for the hoop 20, I

Ends 2t'or the free be limited in sliding movement in clip 14 by contacteither with arms 32 or flanks 30, or both. In the particular designshown in the drawings, the length of the parts is such that ferrule 26makes contact with arms 32 a little beyond the ends of flanks 30.

Referring now more particularly to Fig. 1, it will be evident that thecleaning element, comprising hoop 20 and fabric part 18, may lie at apredetermined angle to.

handle 10 in either direction. Thus the full line position indicates theuse of the cleaner on the floor, but if a baseboard or other dihedralangle is encountered, the parts can be shifted into the dotted lineposition to afi'ord a full bearing surface against such baseboard,without turning the entire tool over. Of greater importance, from thestandpoint of durability in service, is the fact that by rotating thehandle through 180 about its own axis, both sides of the fabric body 18can be utilized with equal effectiveness on the same surface. Theonepiece construction of the retaining clip maend of ferrule 26 111terially cheapens the product both in the 7 cost of material and in theprocesses of manufacture-and assembly, and the liner 14 and ferrule 26greatly prolong the life of V the tool. I

Without further elaboration, the foregoing will so fully explain thegist of my invention that others may, by app-lying current knowledge,readily adapt the same for use under various conditions of servicewithout eliminating certain features which may properly be said toconstitute the essential items of novelty involved, which items areintended to be defined and secured to me by the following claims:

I claim: I v 1. In a cleaner, in combination, a handle, a sleeve at oneend of said handle, a trans verse journal in the end of said sleeve,said sleeve and journal being formed of a single piece of sheet metal,aslot in the endof the handle inside said sleeve lying in a planeoerpendicular to said journal, a jointed cleaning element, the joint ofsaid element lying in said transverse journal, said joint comprisingoutturned ends and a ferrule receiving said ends and lying in said slot,the end of said joint contacting said sleeve to limit pivotal movementof said element.

2. In a. cleaner, in combination, a handle, a sleeve at one end of saidhandle, a transverse journal in the end of said sleeve, a slot in theend of the handle inside said sleeve lying in a plane perpendicular tosaid journal, a cleaning element pivoted in said transverse journal,said element having a projection extending into said slot and engagingsaid sleeve to limit pivotal movement of the element.

3. In a cleaner, in combination, a handle,

a transverse journal at the end of said handle, said handle having aslot adjacent said journal and lying'in a plane generally perpendicularthereto, a cleaning element pivoted in said transverse journal, saidelement having a projection extending into and swingable in said slot,and means cooperating with said projection to limit pivotal movement ofthe cleaning element in said journal.

In Witness whereof, I hereunto subscribe my name this 30th day of June,1924.

ERNEST J. DOHNAL.
